Hi Cognito. I just wanna say that i found your channel recently and... ITS AMAZING! I have exams in two weeks (which are going to be used as evidence for my GCSE's) and I am a very visual learner. I had forgotten how useful videos are to me as a form of revision and this channel has made my revision so much easier - seriously saved my exams! Reading through notes and writing flashcards are just really passive for me and I constantly lose concentration. I love how your videos are short, information packed and engaging. I can't wait to use your website in the near future also! Thank you for making such a difference to my revision!

[eclyptix]

I struggled with this and I figured out a way easy for me

New÷old
To find the multiplier

(Old-new)÷old= answer 1
Then
Answer 1x100=percentage change

This was to find percentage change

I am very grateful, actually I am a high school student and will take the igcse exam. I wish I could find your channel earlier

[lilifabre]

Thank you for the video! One thing though: using this method, please make sure that write that you are multiplying by 100%, not just 100... Otherwise, you are writing that 12.5=0.125 etc.
